Roller Introduction | Transmission Roller | Redirecting Roller | Mechanical Roller | Stamping Roller | Conveyor Line Roller

>Shenzhen Taiyuan Industrial Parts Co., Ltd. specializes in the production of assembly line rollers and industrial conveying accessories. The company has rich manufacturing experience, and its products are of excellent quality, reliable and timely supply. They are widely used in various types of machinery and equipment and automated assembly line companies. The roller is a cylindrical part, divided into driving and driven rollers. It is widely used in various transmission and conveying systems such as rotary screen printing machines, digital printers, conveying equipment, papermaking and packaging machinery. Usually made of seamless steel pipes, materials such as aluminum alloy, stainless steel, duplex stainless steel, steel castings, and solid forged alloy steel cores may also be used depending on different process requirements. The production of rollers mainly consists of the processes of initial rolling of the roller body, initial calibration of static balance, interference assembly and welding of the shaft head, fine turning and fine calibration of dynamic balancing. If the requirements for mechanical tolerances such as roundness, cylindricity and straightness are lower, grinding with a cylindrical grinder or roll grinder is required after finishing. If there are requirements for surface hardness, a heat treatment process needs to be added. After the drum is formed, for the needs of rust prevention, corrosion resistance, wear resistance and support, surface treatment or coating such as spray painting, galvanizing, spray coating, rubber chrome plating, ceramic spraying and oxidation is also required. Classified by size, there are large ones such as rollers for papermaking machinery (the length can reach more than meters, diameters above) and small ones such as flat rollers used on belt conveyors on automatic assembly lines (generally within meters in length). They are also divided according to their functions. Some are used to ensure transfer accuracy, such as the rollers on digital laser printers. Some are used for filtering, such as the calender rollers on papermaking machinery. There are also support rollers that do not require high dimensional accuracy. There are rollers that require heat exchange, and there are also rollers that function as heavy-duty filter presses, etc., which are not listed here. Selection of roller diameter. Selection of roller material: carbon steel, galvanized carbon steel, chromium-plated carbon steel, rubber-coated aluminum alloy, stainless steel, etc. Selection of roller type Unpowered roller, single chain roller, double chain roller, tapered roller, grooved roller. Roller fixing method, spring press-in type, internal tooth shaft type, full flat tenon type, through shaft pin hole type.
